PERFORATING, fiEALING, AND MEASURING DEVICE.

Application filed April 10,

This invention relates to can opening de-' vices and has for its primary object the proopening in the can or container, and amanipulating portion so designed as to simplify the operation of forming the opening and which, incidentally, acts in the dual capacity of a measure or charge holder and aseal, so that after an opening has been formed in the can or container, the device can be arranged in operative sealed engagement with respect to the opening; and which said de vice is freely removable from the opening so that any part of the cans contents can be poured into the measure or charge holding portion.

Another object of the invention is to provide a device of this character which may be operated with little manual effort in the act of forming an opening in the can.

A still further object of the invention is to provide a device of this character which may be operated without causing injury to the hands when forming the opening.

With the above and other objects in view, which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in the claim.

In the accompanying drawings has been i illustrated a single and preferred form of the invention, it being, however, understood that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim mav be resorted to when desired.

Figure 1 is a vertical section through a portion of a can showing an application of the invention thereto to form an opening in the can, the measure portion of the invention being shown dpartly in full lines and partly in section; an

Figure 2 is a top plan view thereof.

The device is admirably useful in connection with metallic cans or containers such as those intended for the temporary storage of ground or pulverized coffee, cereals, condiments and other matter capable of being poured from the container Serial No. 101,180.

when an opening has been formed in one of its walls; or it may be used in' conju'nc tion with receptacles or containers intended to hold medicines, chemicals, d1s1nfectants,

insecticides, etc. We are not particularly interested in the kinds of materials to be employed, nor in the size or proportion of parts, as this may be left to .ordinarydiscretion, according to the purpose to which the invention is to be put.

In carrying the invention into practice, we preferably employ a cupped manipulating portion 5 which is hollow and substantially frustro-conical, the upper large end being open as indicated, and the lower small end closed by a flat bottom 6. The marginal edge of the portion 5 is rolled preferably at 7 and within the roll is inserted a reinforcing wire or strip 8 to give strength to the structure and at the same time offer a marginal surface which will be easy to the palm of the hand when the latter is made to rest thereon.

The portion 5 may be of any appropriate size, but when the device is used in conjunction with coffee cans, the proportion of said portion 5 is calculated so as to constitute a defined measure. For instance, its capacity may be equal to the capacity of an ordinary tea-cup.

axially of the flat bottom 6, and fixedly secured thereto by welding, or in any other suitable well-known manner, is a depending cylindrical punch or penetrating .instru' ment 9 having a straight cutting edge 10 and a connecting spiral cutting edge 11.

This construction gives to the base of the The air when pressure is applied to the device in the act of penetrating a can. The point 12 of the penetrating instrument 9 is now placed in contact with the crown wall A of the can B, and force in a downward direction is applied to the device so that the instrument 9 passes through the crowm and in the act of so doing it forms an opening therein. In coffee cans, it is desirable to form' the opening 13 near the marginal bea-d'of' the crown A so that in the act of pouring the coffee from the can, no great difficulty Will be experienced in a discharge 01"" the entire contents of the can. 7 r I V 7.

hen the opening is formed in the can,

the instrument 9 may normally constitiite a stopper for the opening, and the base 6 ot the cupped portion 5 comes in flat contact with the can to ettectlvely seal the opening in the'i vall A. This is enceedingly desirable in caes Where the contents of the can might be "impaired by undue exposure to atmospheric air VV hen pouring the contents from the can, the cup 5 maybe used as a measure for determining the discharge of material from the can for any purpose sai d portion.

whatsoever; for instance, a predetermined PJYQOHHl] of ground coffee in proportion to so much Water when it is desired to boil the coffee for beverage purposes,

We claim V A device of the class described comprising a perforating instrument adapted to form a pouring opening in a can, and a'manipulating portion secured to said instrument at one end thereof and: provided- With a fiat seat, the instrument serving as a. closure for the opening when formedand thelseat serving. to close over? the opening and to rest against portions of: the can. around the opening, said manipulating portion being of: cup formation having an upper. open end Whose diameter is greater than that of the base of JAMES o. runes. 1 CLEMENS c: 'GOGLE.
